Application filed August 26, 1901.. Serial No. 73,381. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES T. HAWLEY,

a citizen of the United States, and a resident of Hopedale, county of Worcester, State of Massachusetts, have invented an Improve ment in Spinning-Frames, of which the following description, in connection with'the accompanying drawings,=is a specification, like characters on the drawings representing like parts.

This invention has for its objectthe prod nction of novel means for effecting the spinning of yarn upon a yarn-receiver or bobbin in such a way that a preliminary winding or bunch will be laid and thereafter a main or service winding to complete the yarn mass. 4

To this end my invention has more particular relation to the builder-motion of a spin-Q ning-frame,'and the various novel features of construction,arrangement, and operation embodied in my present invention will be fully described hereinafter, and particularly pointed out in the following claims.

Bobbins or filling-carriers provided with a.

bunch and a service winding of yarn are principally used in the shuttles of automatic filling-replenishing looms of the feeler type,

the filling being replenished by or through the action of afeeler when the yarn has woven offdown to the bunch in a manner well known 1 to those skilled in the art. r 1

Figure l is a front elevation of one end of a spinning-frame, showing the builder-motion with one embodiment of myinvent-ion applied thereto. tion on the line 2 2, Fig. 1, looking toward the left.

is a transverse section onthe line 5 5, Figs.

2 and 4, looking in the direction of the arrow Fig. 2 is a transverse S605 Fig. 2 is an enlarged detail in side elevation of a portion of the mechanism shown Fig. l.

, 5, but on a scale corresponding to Fig. 4. Fig. 6 is an enlarged detail of a portion of the builder-arm looking toward the right, Fig. 4,

showing the bunch and service winding camfollowers. Fig. 7 is an enlarged plan view, partly broken out, of a detent-pawl and its carrier, illustrated in Fig. 2 as mounted on the follower rock-shaft and omitted in Fig. 4 for the sake of clearness, said pawl forming part of the means for governing automatically the change from bunch to main or service win'ding. Fig. 8 is an inner side elevation of one of the component members of such means to be described; and Fig. 9 is an outer face view of a cooperating member, the membersshown in Figs. Sand 9 being illustrated in plan in Fig. 4.

Rerferring to Figs. 1 and 2, the end frame A, spindle-rail R on which are mounted the rotatable sleeve-whirl spindles S, the vertically-reciprocating ring-rail R, provided with the pawl m with the ratchet or pick wheel on byintermittent engagement of the pawlwith an actuator 'm during the laying of theyarn upon the yarn-receiver orbobbin B, the worm-' shaft rotating the drum m and gradually letting off the chain m connected in usual manher with the rocker R which operates the lifter-rods L, one of which only is shown in In said figure the apparatus is shown as efiecting the winding of the bunch, and during such winding the actuator m preferably will not engage and operatethe pawl m, so that the ring-rail does not rise a little higher at the upper end of each stroke, as it does later when the filling is being laid to form the main or service winding and with the actuator m intermittingly engaging the pawl m. The bunch or preliminary winding (see Fig. 3) is thus wound with a short traverse, and the main or service windin g w, Fig. 3, is laid with the filling-wind and with a longer traverse, and to effect the two windings I have herein provided two separate actuating devices to cooperate with the builderherein shown as two'cams P M, fast upon the cam-shaft O ,theformeractuatingthebuildermotion during the laying of the preliminary winding or bunch and the latter during the laying of the main or service winding of yarn upon the yarn-receiver, and herein the cam M is shown as a heart-cam of usual construction and adapted to lay the yarn with the fillingwind, one complete revolution of the cam effecting a complete reciprocation the ring-rail. The bunch-winding cam P, however, is shown as having a plurality of high and low points, (see Fig. 2,) one of the low points being shown at p and the corresponding high point at 10 rotation of the cams being eflected in the direction of the arrow 10, Fig. 2, and consequently one complete rotation of the cam P will effect a number of complete reciprocations of the ring-rail, corresponding to the number of corresponding high and low points thereon, the bunch being laid with a corre-' sponding number of traverses.

The builder-arm is provided with a laterally-offset bracket B (see Figs. 4, 5, and 6,)

provided with a boss 11 to form an outer hearing for a short rock-shaft cZ the inner end of the rock-shaft being extended through and having a bearing in a depending ear b on the builder-arm. (Shown in Fig. 2.) The said rock-shaft has rigidly secured to it two rockerarms d (1, provided with laterally-extended rolls or followers 10 m to cooperate one at a time with the cams P M, respectively, the followers being set at an angle to each other on the rock-shaft, as best shown in Figs. 1 and 6. The follower 10 is adjustably mounted in thc armd, as shown in Fig. 6, having its stud 12 extending through a longitudinal slot 13 in the arm and is rigidly held in adjusted position by a set-nut 14.

.ables the location of the bunch to be adjusted This adjustment enon the yarn-receiver or bobbin, as the'adjustment of the follower toward the rock-shaft d will cause the bunch to bewound higher up on the bobbin, whereas opposite adjustment .of the follower will have the efiect of laying the bunch nearer the head of the bobbin. At its inner'end the rock-shaft b has rigidly secured thereto by set screws15 a hub (1 having a peculiarly-shaped upturned ear (1 (see Fig. 2 provided with a lip or flange d, a portion of which is eccentric with a stud d secured to the ear and extended laterally therefrom, said stud serving as a fulcrum for a pawl-carrier d, (see Figs. 2, 5, and 7,) the pawl-carrier being shown as an upturned arm having a lateral offset 01, terminating in a hub (1 in which hub is mounted a stud (1 (see Fig. 7,) the stud having rigidly secured to it a pawl d. A coiled spring 5 Fig. 7, surrounds the stud d and at one end it is securedto the hub (1 the other end of the spring being attached to a sleeve (1, pinned to the stud. The winding of the spring is such that the back of the pawl is normally maintained against the end of aset-screw 16, mounted in an car 17 of the hub 01 and held in adjusted position by a check-nut 18.

The pawl-carrier d is provided with a locking-dog (Z Figs. 5 and 7, fora purpose to be described, and the lower end of the pawl-carrier, as shown clearly in Fig. 2, is made to fit the curved portion of the flange (2, while a tangent portion or shoulder 19 on the pawlcarrier adjacent its fulcrum d is adapted to at times cooperate with the straight or tangent portion 20 of the said flange to limit downward movementof the pawl-carrier relative to its supporting-hub d The cam-shaft C has loosely mounted upon it a ratchet-wheel O, prevented from movement longitudinallyin one direction bya collar 22, fast on the cam-shaft, and adjacent the. said ratchet-wheel a cam-disk E is also mounted on the cam-shaft to rotate there with, but longitudinally movable thereupon, and herein I have shown the disk as having on its outer face relatively to the ratchet U a lateral lug e, which is extended betweentwo cars 23,. secured to or forming part of a collar 24, rigidly secured to the cam-shaft, the sliding connection between the lug e and cars 23 permitting longitudinal movement of the disk E on the shaft and also effecting itsrotation therewith, a spring S coiled around the shaft between the hub of the disk E and the collar 24, acting normally to press said disk toward the ratchet O. A segmental cam e is formed on the inner face of the disk concentric with the shaft O the leading end of the cam being inclined, as at 6*, Fig. 8, from the face of the disk to the top or parallel face of the cam to permit a codperating follower lug c on the adjacent face of the ratchet G to pass from the face of the disk E- up ontothe cam e, when relative rotative movement of the ratchet and disk is eifected, the shape of the follower (1 being best shown in full lines, Fig. 4, and dotted lines, Figs. 5 and 9. Referring to Figs. 4 and 5, wherein the follower c is shown as traveling on the fiat surface of the cam e, it will be manifest that at such time the disk E will be pressed toward the builder-arm against the action of the spring S and it will also be manifest that when the follower 0 drops off the abrupt end 0 of the cam the said spring will instantly f (see Figs. 4 and 5,) which is mounted in a bearing 19 secured to a dropped or depending part b of the builder-arm, a spring 8 (see Fig. 4) surrounding the rear end of the stud and being attached at one end to the bearing 6 and at its other end to a sleevef pinned to the stud, the spring normally acting to throw the finger f toward the outer face of the disk E. The arm f is provided with a notch f to be at times engaged by the locking-dog (1 as clearly shown in Fig. 5, and remembering that this dog is a part of the pawl-carrier d it will be manifest from an inspection of Figs. 2 and 5 that when the dog is in engagement with the notch f the pawl (1 will be positioned to cooperate with the ratchet 0 whenever the builder-arm is raised sufficiently to bring the pawl into the position shown in Figs. 1 and 2.

An arm h, fulcrumed at 71) in an ear a on the part A of the main frame, is extended laterally therefrom toward the builder-arm, and at its free end is downturned adjacent the peripheries of the ratchet C and disk E, (see Figs. t and 5,) and said arm has secured to or forming part of it a notched plate h, which embraces the periphery of the disk,and a downturned finger 72?, carried by the arm h, is at certain times brought into the path of movement of a lug c on the outer face of the ratchet G, the movement of the disk E longitudinally of the cam-shaft swinging thearm h on its fulcrum to move the finger or stop 71. into or out of the path of movement of the said lug c and when in the path of the lug, as illustrated in Figs. 4 and 5, it will be manifest that when the lug engages the finger rotation of the ratchet will be stopped until the finger is withdrawn from operative position.

Having described in detail the mechanism illustrated in the drawings, the operation of the apparatus will now be described, itbeing noted that the parts are shown in the drawings in the position they occupy during the formation of the bunch or preliminary winding. The frictional connection between the disk E and the ratchet 0 acts to rotate the latter unless it is retarded or prevented, and during the winding of the bunch the pawl d is at each upward stroke of the builder-arm brought into position to engage and stop the rotation of the ratchet, the disk E rotating continuously with the cam -shaft, so that after a predetermined retardation of the ratchet, effected by the intermittent action of the pawl, the follower-lug 0' will ride up on the incline e and onto the cam e, whereupon the disk and ratchet will have been laterally separated sufficiently to bring the releasinglug c on the outer face of the disk E into position to act upon the finger f and disengage or release the locking-dog d from its holding-notch f in the arm f such release of the dog permitting the pawl-carrier d to swing downward on its fulcrum at until the shoulder 19 abuts against the tangent portion 20 of the flange 61 thus moving the pawl d down, so that it cannot engage the ratchet G on the next upward swing of the builderarm and also releasing the follower rockshaft d During the winding of the bunch the actuating or traverse cam P is acting upon the follower 19 At such time a lug (1 depending from the follower rock-shaft d abuts against a stop (see Fig. 6) on the bracket B When the rock-shaft d is released and before complete change from bunch to service winding takes place, the two followers will to a certain extent cooperate simultaneously with their actuating-cams, and the builder-arm will be actuated by the joint action of such cams, the followers being so set that at the time of release both will be in contact with their respective cams. Thereafter to change automatically the mechanism frombunch to main or service wind-- ing the respective followers 10 m will cooperate with the low point m of the cam M and at or near a low point p of the bunchwinding P, respectively, so that both cams will act upon their followers to throw. them in the direction of the arrow 70, Fig. 6, swinging the arm at into upright position and moving the arm at down and the follower p out of cooperative engagement with its cam, the main windi-ngcam M thereafter operating through its follower 011 to effect the movement of the builder-arm, and at such time the arm d will be thrown against a stop 80 (see dotted lines, Fig. 6) on the bracket B .This change of the control of the builder-arm from the bunch-winding cam to the main-winding cam does not take place at the instant that the dog d is released from its holding-notch, but somewhat after this has been released, as will be manifest from an inspection of Fig. 2, wherein such release is just about to be effected; but it will be seen that the actuatingcams P M are relatively positioned, so that the throw of the follower rock-shaft b will not take place until the cam-shaft O has made about three-quarters of a revolution from the position shown. Referring to Figs. 4 and 5, it will be seen that while the follower-lug c is traveling over the flat surface of the segmental cam e the stop-finger It will be in the path of the lug c and will hold the ratchet C from rotative movement, and the ratchet will be so held until the disk E has turned far enough to permit the follower c to drop off the end 8 of the cam e and between such end and the lug 6 When this takes place, the spring S immediately acts to move the disk E toward the ratchet, and, as has been described, the arm it will thereby be swung to move the-stop-finger 77.2 from engageinent with the lug c and the ratchet will 'for each complete rotation of the cam M,

downward still farther.

and during the entire main winding the pawl d will be out of engagement with the ratchet. It will be remembered that there is a preliminary movement of the pawl away from the ratchet, due to the release of the lockingdog (1 from its holding-notch f and subsequently when the follower rock shaft d is turned to bring the follower m into operative position the pawl-carrier 01 will be swung After the winding of the yarn has been completed and the yarnreceiver or bobbin filled the parts will be in position ready for the starting of a new bobbin or set of bobbins. The attendant will then swing the pawlcarrier 01 upward to bring the locking-dog into engagement with its holding-notch f thereby swinging the follower rock-shaft cl to bring the bunchwi'nding follower 19 into position to cooperate with the cam P, and at the same time the pawl d will be moved into position to cooperate with and intermittingly arrest rotative movement of the ratchet O at each upward movement of the builder-arm, and the spring 8 which normally holds the pawl 01 in position against its adj ustable back-stop or setscrew 16, will yield if for any reason the upward movement of the pawl should be interfered with, and thereby prevent any breakage of the parts. This spring also operates, in connection with the adjustable back-stop 16, to regulate the extent of retardation of the ratchet G by or through engagement with the pawl. If the back-stop is set up so that the pawl will come into engagement with the ratchet later as the builder-arm is lifted and leaves it sooner as the builder-arm descends, it will be manifest that the retardation of the ratchet will be less than if the pawl were ad'- justed, through its back-stop, to engage the ratchet earlier and leave it later in the rise and fall of the builder-arm.. The longer each retardation of the ratchet, due to engagement with the pawl, the shorter will be the time which must elapse before the follower-lug 0 will be brought into position to cooperate with the cam e, and consequently the less vyarn will be laid in forming the bunch or preliminary winding.

completed the simple movement of the pawlcarrying arm cl into operative position will insure the winding of the bunch when the frame is again started. The resetting referred to is accomplished by means of the stop-finger h and lug c on the ratchet, as

thereby the relative angular position of the disk E and ratchet is changed so that they will be properly set relative to each other for the beginning of the bunch winding for the next set of bobbins. The change from bunchwinding to main or service winding is automatically eifected, as has been described, by or through the simultaneous action of the two traverse or actuating cams upon their respective followers mounted on the builderarm at one point in the rotation of the mainwinding cam, the follower rock-shaft 01 being at that time free to be rocked. The movement of the followerlug 0 into the space between the heel e of the cam e and the projection e is effected at the instant the stop-finger h is moved to release the ratchet O, and the latter rotates in unison with the disk E during the main or service winding. When the next bunchwinding is started, the first arrest of the ratchet bythe pawl d causes the lug c to ride up over the projection e and onto the face of the disk E beyond said projection, thus always insuring a given relative angular position of the ratchet and disk at the beginning of the winding. of the bunch.

I have herein shown and described one practical embodiment of my invention, and Various changes or modifications thereof may be made by those skilled in the art without departing from the spirit and scope of my invention.
